2 Claims. (Cl. 292-347) This invention relates to latch assemblies fordoors and more particularly to a novel means for firmly securing therose of a knob assembly wherein it is possible to entirely conceal allattaching means and at the same time adapt the rose plate totelescopically enter the knob.

Door latch assemblies, particularly those used in ofiice buildings anddwellings must be highly ornamental in-appearance. This demand for anornamental appearance requires a product having as neat anduninterrupted a surface appearance and design as possible. In the designof articles to obtain this desired goal, emphasis is placed upon theconcealment of all functional elements particularly where they are notsubject to ornamental design or camouflage.

In the elimination of all outwardly appearing anchoring means such asscrews, two important factors must always be considered. The first ofthese factors is cost. Whatever device is utilized to replace theseanchoring means must be simple to manufacture and economical both inmaterials used and manpower required to assemble the necessary parts.This requirement in itself is suificient to prevent the use of manystructural arrangements normally employed for concealment where cost isnot such an important factor. The second important factor is simplicityof assembly at the time the latch structure is mounted to the door. Thelatch assembly must be so designed that even an unskilled workman canreadily and rapidly assemble and mount the structure without becomingconfused and without the necessity of special tools. It has been foundthat complicated assemblies are frequently injured or returned asinoperative by the men installing them, merely because carefully wordedassembly and mounting instructions were not heeded.

Wholly aside from the ornamental features of my invention, is thedesirability of providing a watertight handle assembly. When the handleis used on the exterior of a structure, it is subject to rain, fog andsnow. Since the internal operating mechanism of the handle, normally, isof steel the entrance of moisture is highly detrimental. By making therose plate and the cover for the knob shank an integral part andextending the knob shank cover into the knob, all vertical joints in theexternal structure are eliminated. The joint between the shank cover andthe knob is horizontal. Therefore, it does not readily admit water tothe interior of the lock structure.

It is a primary object of my invention to provide a latch structure inwhich all mounting means for the rose plate are entirely concealed by astructure which is both simple to install and economical to manufacture.It is a further object of my invention to provide a structure which maybe simply removed after initial installation should repairs or othercircumstances require such removal. My invention contemplates anassembly permitting the quick spacing of the rose plate from the doorface for painting of the door. Other objects include improved climaticresistance and integration of parts to reduce manufacturing costs.

Other objects and purposes of my invention will be "ice readily seen bythose acquainted with the design and manufacture of hardware for doorsupon reading the following specification and the accompanying drawings.

In executing the objects and purposes of my invention, I have provided ahandle assembly including a base plate securely mounted to the face of adoor. The base plate includes an outwardly projecting, tubular shankdesigned to rotatably and slidably receive the tubular sleeve of a knob.The knob and its sleeve are securely but detachably anchored to thestationary base plate by means which, when the rose has been finallymounted, are entirely concealed. The means for assembling the knob tothe base plate is concealed by a rose. This rose slidably seats aboutthe shank of the base plate and may be moved axially of this shank intothe knob to reveal the knob anchoring means whereby the knob may beremoved. The rose itself is securely held in position by concealedfasteners such as a resilient clip.

In the following description the terms inwardly and outwardly arefrequently used and are to be taken to mean inwardly toward the centerof a door and outwardly away therefrom. In the following description theterms inwardly and outwardly are used as if the handle assemblydescribed were mounted on the outer face of a door.

Referring now to the drawings in greater detail, the numeral 1 indicatesa generally circular base plate having an outwardly extending peripheralflange 2 (Figures 1 through 4). The flange 2 is turned back upon itself,forming a groove -3 opening radially inwardly toward the center of thebase plate 1. The base plate 1 has a central aperture 4 (Figure 2) aboutwhich extends an inwardly ofiset depression 5. The holes 6 in the baseplate 1 permits the base plate to be secured to the face of a door 8 bysuitable fastening means such as screws 7.

Mounted to the base plate 1 is an outwardly extending, tubular shank 10.The shank 10 has, at its inward end, a radially extending lip 11 seatedon and secured to the base plate 1 (Figure 7). Immediately outwardly ofthe lip 11 is the radial collar 12 of greater diameter than the mainportion of the shank 10. Where the main portion of the shank joins thecollar 12, the inner shank has a shoulder 13.

The grip portion of the handle assembly is a hollow knob 15 providedwith an aperture 20 on its inward side. The hollow knob 15 is reinforcedby an internal reinforcement 19. The aperture 20 is closed by means ofan annular cover 21 having a peripheral rim 22, designed to engage theedge of the aperture 20 and detachably secure the a a; cover 21 to thehollow knob 15. The cover 21 has a central opening 23 of greaterdiameter than that of the shank 10. About the central opening 23, thecover 21 is flanged at 16, the flange 16 extending into the interior ofthe knob. Rotatably seated within the shank 10 is the tubular knobsleeve 14. The knob sleeve, at its outward end, is concentricallysecured to the inner surface of the hollow knob 15. The knob sleeve 14extends through the opening 23 in the cover 21 and is secured to theinner surface of the outward wall of the knob.

The base plate 1 is surrounded and covered by a rose plate 24. The roseplate 24 consists of a large, circular cover portion 25' at its inwardend and a tubular, outward extension or shank 26 of such diameter thatit will slidably receive the shank 10 and pass through the opening 23inthe cover 21. The rose plate 24 is essentially an ornamental cover forconcealing the internal, functional structure of thehandle assembly, thecover or flared portion 25 covering the structure adjacent the door andthe shank or tubular portion 26 covering the outwardly extending knobmounting structure. The rose plate 24 also. serves as a weatherresistant housing for the internal mechanism.

Seated within a major portion of the groove 3 at the periphery of thebase plate 1 is a wire element 30. The wire element 30 has a portionextending across the base plate 1 to one side of the. center thereof(Figures 2, 3 and 4). Adjacent each end of this portion, the wireelement 30 is secured to the base plate by a clip 32. Although they maybe made as separate parts, preferably, the clips are punched out of thebase plate as fingers having one free end and bent outwardly to seatover and clamp the wire element between them and the outward face of thebase plate. Between the clips 32, the wire element 30 is formed into anoutwardly extending loop 33. Mounted on the inner surface of the coverportion of the rose plate 24 is an inwardly projecting, resilient,striker element 34. The striker element 34 is designed to engage theloop 33. The striker element 34 and the loop 33 constitute the twooperating parts of a friction latch.

Mounted in the radial collar 12 and seated in the depression of the baseplate 1 is a cup 40. The cup 40 is of such diameter that it may receivethe knob sleeve 14 therein. through its inward face, through which passthe projections 42 on the inward end of the knob sleeve 14 (Figure 8).The'cup 40 has an inwardly projecting, non-circular stem 43 for engagingand operating the roll-back of a latch assembly. When the handleassembly is designed for use with a key-in-knob type structure, such asthat disclosed in'co-pending application, Serial No. 47,438, entitledKeyin-Knob Lock, filed September 2, 1948, now Patent No. 2,642,735,dated June 23, 1953, inventor Herbert Quigley, the stem is hollow. Whenthe handle assembly is designed for use with other types of locks thestem 43 may very well be solid.

Seated within the inward end of the knob sleeve 14 is the locking ring44 having a projection 45 on one side. T he'locking ring 44 is urged inthe direction of the projcction 45 by the spring 46. The projection 45,under the urging of the spring 46, passes through an opening 47 in theside of the knob sleeve 14 into the opening 48 in the side wall of thecup 40. A pair of diametrically arranged access openings 49 are providedin the inner shank whereby access may be had to the projection 45. Theaccess openings 49 are appreciably larger than the openings 47 and 48 tofacilitate the entrance of a standard tool such as a screw driver.

The cup 40 as well as the knob sleeve 14 is freely rotatable withrespect to the base plate 1 and inner shank 10. The spring 46 is heldagainst movement axially of the knob sleeve 14 by the channel 50 in theinner surface of the knob sleeve in which one portion of the spring isseated. The cup 40, locking ring 44, spring 46 and the various aperturescooperating with these parts constitute the knob anchoring assembly andare not'part of the The cup 40 is provided with arcuate slots 41-invention forming the subject matter of this application but are brieflydescribed herein for the purpose of making a complete disclosure of theoperation and purpose of my invention. The knob anchoring assembly isfully disclosed and claimed in my co-pending application Serial Number274,432, filed on March 1, 1952, and entitled Concealed Knob Anchor.

The rose plate 24 is, at a point radially aligned with the strikerelement 34, provided with a notch 54 in its outer edge (Figures 1 and6). The notch 54 is of such length and width as to permit the insertiontherethrough of the tip of a conventional, medium sized screw driver.

Operation In the assembly of my invention upon a door, the base plate 1with the shank 16 secured thereto, is mounted on the face of a door bymeans of screws 7. Preferably, the base plate 1 is so oriented that theloop 33in the wire element 39 is at the lower end of the base plate. Bythis arrangement the notch 54 in the rose plate 24 is located at thebottom of the handle assembly Where it is substantially concealed. Therose plate 24 is then seated over the shank 10 with the resilientstriker element 34 aligned with the loop 33. When the striker element 34contacts the loop 33, inward movement of the rose will cease. At thispoint, additional pressure is put upon the rose to cause the strikerelement 34 to bend radially outwardly so that it may pass the loop 33.This permits the rose to move inwardly against the face of the door. Thestriker element will then snap radially inwardly on the inward side ofthe loop 33, securely holding the rose plate 24 against outward movementaway from the door. The outwardly extending collar portion of the roseplate seats around the shank 10, preventing the rose plate from movingsideways to a position eccentric of the shank 16. Thus, the rose plateis held se-' curely in position. It will be recognized that the loop 33can be made resilient and the striker element 34 rigid whereby the looprather than the striker element flexes.

After the rose plate has been put in position, the knob assembly, withthe projection 45 depressed, so that it will not interfere with theentrance of the knob sleeve 14 into the shank 10, is assembled to theshank 10. When the knob sleeve 14 has been passed all the way down theshank 10, the projection 45 will, in an inward and outward direction, bealigned with the opening 48 in the side Wall of the cup 40. Uponrotation of the knob until the projection 45 is circumferentiallyaligned with the opening 48, the spring 46 will force the projection outthrough the opening 48. The resistance of the roll-backs will hold thecup from rotating during this aligning process. Thereafter, the knobsleeve 14 and the cup 41 are securely held together by the projection45. The knob assembly is held against outward movement by the shoulder13 which prevents outward movement of the cup 40.

When the knob assembly is to be removed, a screw driver or similar toolis first placed in the notch 54 in the rose plate 24. The screw driveris rotated to pry the rose plate outwardly, disengaging the strikerelement 34 from the loop 33. The rose plate 24 may then be pushedoutwardly with the collar portion of the rose plate passing through theopening in the cover 21 into the interior of the knob (Figure 10). Thispermits the rose plate to be moved outwardly sufliciently that the knobassembly may be released by passing the end of a'screw driver or similartool through one of the access openings 49 in the shank .16 to force theprojection inwardly to disengage the cup 40. Once the projection 45 andthe cup 40 have been disengaged, the whole knob assembly may bewithdrawn and thereafter the rose plate 24 may be withdrawn merely bypulling it outwardly over the end of the shank 10.

It will be recognized that the telescoping of the rose shank into theknob has, within itself, numerous functional and structural advantageswhich are independent of the concealed anchoring arrangement. Thus, thisdesign for the rose plate may be used with exposed attachment means(Figure 11). In the structure shown in Figure 11, the rose plate 24a issecured to the base plate by screws 30 engaging suitable bosses 81 onthe base plate 10. Upon removal of the screws 80 the rose plate 24a maybe telescoped outwardly into the knob 15.

It is seen that my invention provides a simple yet positive means forconcealing the entire functional structure at the base of the handleassembly as well as the anchoring means for the rose plate. At the sametime, the en tire shank portion of the handle assembly from the doorface of the knob is covered by a single, imperforate cover, protectingthe internal mechanism against moisture or other physical injury. Thetelescoping of the rose into the knob permits the rose to besuificiently spaced from the door face, Without removal of the knob, toallow the door to be painted without injury to the hardwares finish. Itwill be recognized that although I have described one particularstructure whereby the knob assembly may be detachably secured to a doorin a manner entirely concealable by the rose plate, numerous other typesof structures may be utilized for eifecting the anchoring of the knobassembly without in any way affecting my invention.

It will be recognized that various modifications of my invention may bemade each without departing from the principle of my invention. Each ofthese modifications is to be considered as included in the hereinafterappended claims unless the language of these claims expressly providesotherwise.
